(Version 4.0 Beta 3 (Build 55153))

LIBERTYFORALL1776  Needs Apple Address Book support, Address Book plugin, Growl support, and it's still not 64-bit! Also, I cannot get incoming call ring audio on this beta 3 or the 3.x version! Anyone know a fix?

XPLICIT  Best free SoftPhone for Mac. Ok, the interface is not Mac-like, in fact a bit ugly but that doesn't matter. iSoftPhone is buggy and laggy, Zoiper is just a little but still buggy. X-Lite works well and that's it for me.

BRENK  i searched all the time for a sip softphone too. i bought the eyebeam software - but there were no updates since a year...

isoftphone is a little bit expensive...

so i found the sip softphone called "zoiper" last month - it works fine with my sip accounts...

BILLCOYOTE  My version 2.0 works great with Leopard. :-)

TOM MARVOLO RIDDLE  iSoftphone isn't bad... but yeah... you are right, there aren't much alternatives out there... what a pity

TOM MARVOLO RIDDLE  DOES NOT WORK ON LEOPARD!  
(Version 3.0b39984)

TOM MARVOLO RIDDLE  X-Lite is absolutely not Mac Native and therefore quite ugly.

Well, but this is the only Client I got to work with my Provider, so I have no choice.

VEGGIEDUDE  I love this SoftPhone. It works with RingCentral's DigitalLine service. I haven't tried the extra features, such as recording and the like, but as far as calling and receiving calls, it works.

SAGO  you are right FELIX FI, thanks for the suggestion about Xmeeting, it's way better.

don't use this crap, go Xmeeting.  
(Version 3.0b39418)

FELIX-FI  My point is just that somebody was claiming in an earlier comment that X-lite was the *only* free SIP client...  
(Version 3.0b39418)

FELIX-FI  xmeeting is free... and works perfectly.

MRGANDO  no new version since 2004? give me a break, this thing has some damn bugs, its a very nice app , but it is buggy.  
(Version 2.0)

TOMACTO  NOT COMPATIBLE WITH INTEL.

I checked the forum on the developer's website, and I read: "There are no plans for X-Lite and IntelMAC."

This is a shame as this is the only free SIP client for Mac!

SEBASTIEN  After reading the first review for X-lite i stoped and went looking for another sip client. But after findid none to my liking i came back i tried it. It works fine and voice quality is great!

you can use it with a stanaphone account, vonnage account and alot of other sip based sevices or just on a lcal network or the internet.

THOMAS  I just tried this today. It froze up and crashed when trying to register an account through the app. The dialer interface wasn't very MacOS X friendly anyway. Don't bother with this poor windows port.

Their PhoneGAIM app looked like a viable cross-platform replacement for ichat. Alas, it is Linux only, how short sighted.  
(Version 2.0)

HELIXBLUE  I've been using X-Lite now for a week with BroadVoice as my VoIP provider. Overall, an excellent application.

The preferences UI could use some work, and it should really be integrated into AddressBook. Thankfully, there are AppleScripts to make a half-hearted attempt at integration available.

For the price (free), this application is well worth it. I think they should consider including a settings URL import option that allows you to import settings from your provider, rather than having the user input all of the confusing configuration options.

BOSIE  A few days ago i downloaded this (big headache)

X-Lite_Install.dmg

Yesterday I downloaded this (worked first time!)

X_lite-Xten-Mac-1103m.dmg

I'm not sure if the former was pulled but the latter is great. I changed my mind about the app.  
(Version 2.0)

BOSIE  I have a feeling X-Lite is still very much at development stage. Having spent several hours over two days the phone is unable to connect to my VOIP provider, London Voice and Data Exchange despite having all the required data for the SIP proxy. There is a support forum http://support.xten.net but no replies to any of the many questions posted (so no support I'm afraid). Still it is a free app so nothing lost in trying but be very cautious about paying for X-PRO when X-Lite is failing. On the plus side the phone looks good, interface a little cluncky but easy enough to understand. On the negative side 'Diagnostic Window' reveals nothing more than the port you're connected on, SIP 5060, RTP 8000 it is not a verbose connection log. Since I couldn't get the phone to work I will mark down features and ease of use even though the menu is promising.

ANONYMOUS  I completely disagree, but then my clientele and customers need simplicity like this. As an ISP/ASP, I have been looking for a solution just like this, and once our hardware is installed look forward to deploying this. Just my $.02, though.  
(Version 2.0)

CLOUDSCOUT  I agree with the previous comment. The UI is needlessly complex. Granted, this is cross-platform software so Mac-oriented customization is not likely, especially in the free version... but I think the developer could take a leadership role in Macintosh VoIP and reap some rewards.

A simple, clean interface would be preferable. Forget about legacy devices. It need not look like a telephone on the screen. It should have a keypad for interacting with touch-tone services but the interface should be streamlined. Have the keypad as an option that can be clicked on-and-off to save screen real estate. Make the onscreen footprint small so that it can just sit there running in the background.

Integration with Address Book is essential. Give it the ability to be managed by external applications as well. I'd love to have an option in BuddyPop that would let me dial a number with X-Lite.

I'm sure these things have been hammered to death in the developer's forums but I thought I would mention them here as well.

ANDREAS  Works OK but has a horrible non-standard interface. Who needs big on-screen keys with a keyboard in front of him? Ditch the mobile look and build something useful! Look at the Skype interface - that's how a VoIP phone for a computer should look like.
